Working Pressure: 10,000 psig (689 bar)
■ Operating temperature
PTFE: from -65℉H to 450℉H (from -54℃ to 232℃)
Graphite: from -65℉H to 1,200℉H (from -54℃ to 649℃)
■ One-piece forged valve body structure
■ Two-section valve stem design: the thread of upper stem has gone through special hardening treatment, and
the surface of lower stem has gone through buffing and hardening treatment
■ Lubrication on screw thread of upper stem is isolated with dielectric system
■ Up-and-down motion of non-rotating lower stem is replaced by spiral lifting, which reduces friction on packing
in each stroke.
■ Non-rotating lower stem reduces occlusion between valve seat and valve head
■ The fully open b is equipped with back sealing function
■ Optional panel installation
■ The handle is locked with locking bolts at both sides. It is firm and durable
■ Optional handle color
■ Each valve has gone through sealing test in factory by nitrogen in the maximum working pressure
